According to the International Energy Agency's 2050 scenarios, to meet carbon dioxide reductions in line with an acceptable two degrees Celsius increase in mean global temperatures, the current use of nuclear power could be scaled up from around 370 gigawatts today to around 2,000 gigawatts.

Generatıng Change More time and money is spent on nuclear power than any other form of energy. Yet its generating capacity – even with new reactors – and potential contribution to cutting greenhouse gasses, is much less than other methods. The funds should follow tried technologies offering greater returns. t HE POTENTIAL ROLE OF NUCLEAR continues to dominate the energy debate. This is extremely unfortunate as this does not reflect nuclear’s current or potential contribution to the energy mix. Nuclear power provides Britain with around eighteen percent of its electricity, nine percent of energy production, but just 3.5 percent of the final energy that is consumed. The difference between energy production and consumption results from the energy lost during transformation and transmission. For this source of POWER result in only six percent of the required overall emissions reduction. At very best, nuclear power can only ever have a minor role in reducing greenhouse gas. This theoretical assumption excludes the wider environmental and economic implications and in particular those relating to the proliferation of nuclear weapons usable material, the transfer of dual-use, civil-military technology, and the availability of high concentration uranium, that will potentially restrict the use of nuclear power, in particular on this scale. Energy efficiency is the most important means identified power to make a significant contribution to British and, by the International Energy Agency to create a stable climate. more importantly, global energy supply, its use would Supply and demand efficiency and fuel switch measures have to increase enormously. account for approximately half the potential savings. According to the International Energy Agency’s 2050 Renewable energy provides the second largest share of future scenarios, to meet carbon dioxide reductions in line with emissions reduction, at more than twenty percent. This an acceptable two degrees Celsius increase in mean global effectively means that greater supply and demand efficiency, temperatures, the current use of nuclear power could coupled with the greater use of renewabl
